The Shelly Plug M Gen3 is a smart indoor Wi-Fi socket that combines conventional switching functions with modern technology. In addition to remotely controlling connected devices, the plug provides integrated power measurement and Matter support for seamless integration into smart home systems such as Home Assistant.

Installation and setup

Installing the Shelly Plug M Gen3 is straightforward. The smart plug is inserted into a conventional 230-volt socket. An electrical device can then be connected, provided that the maximum load of 3,000 watts or 13 amps is not exceeded. This makes the plug suitable for lighting, household appliances and other typical electrical loads in living areas.

Setup can be performed either via Wi-Fi (2.4 GHz) or using the Matter smart home standard. The device also features Bluetooth, which makes initial configuration much easier because the smartphone can detect the plug directly and add it to the network.

No separate hub is required for operation within the Shelly ecosystem. The device works independently over Wi-Fi and can be controlled directly via the Shelly app or the local web interface.

To integrate the plug into an external smart home platform such as Home Assistant, a compatible Matter controller such as the Echo Show 8 is required.

Matter support: Cross-platform integration

A key advantage of the Shelly Plug M Gen3 is its support for Matter, a manufacturer-independent standard that ensures interoperability between different systems. Provided that a suitable Matter controller is available, the plug can be integrated into the following Matter-compatible systems:

• Apple Home
• Google Home
• Amazon Alexa
• Samsung SmartThings
• Home Assistant

After successful pairing, the device appears in the respective platform as a switchable socket. Communication takes place locally over the IP network. It is important to note that the Shelly Plug M Gen3 is not a Thread device; it uses Wi-Fi as its communication standard.

Overheating protection – safety first

The Shelly Plug M Gen3 features integrated overheating protection with an internal temperature sensor that continuously monitors the operating temperature. If a critical value is reached, the device switches off automatically to prevent overload and possible damage. This safety function operates locally on the device and remains active without an internet connection, providing additional operational safety, especially for high-power appliances.

Monitor energy consumption in real time

A key feature of the Shelly Plug M Gen3 is its integrated energy and power measurement. The device displays the current power draw in watts in real time and stores consumption data.

This function enables the targeted analysis of individual electrical loads in the home. Energy-intensive devices can be identified and automatically switched off when necessary. Power measurement offers practical added value, particularly as energy costs continue to rise.

Automations and local control

The plug supports schedules and automations. Devices can be switched on or off automatically at defined times. Advanced features such as HTTP commands, MQTT and webhooks are also available.

Because the Shelly Plug M Gen3 operates locally on the network, its basic functions remain available without a cloud connection. This improves reliability and enables direct communication within the home network.

Conclusion: Is the Shelly Plug M Gen3 worth it?

The Shelly Plug M Gen3 combines Wi-Fi control, power measurement and Matter support in a compact format. Local control without a hub and integration with popular smart home platforms make the device highly versatile.

For users looking for a smart socket with energy monitoring and open system integration through Matter, the Shelly Plug M Gen3 offers a modern technical solution at a competitive price.
